By embodiment, the present invention will be described in detail for following part, but is not considered as that present invention is limited only to these illustrative implementations Example.
Embodiment
The example that can be used for manufacturing the laminate of the pipe with sightless latasuture is shown in detailed below:
Before by pipe forming process, need to cut laminate with 45 ° to 60 ° of predetermined angular.Without using in addition Synthesis film strips in the case where, since the conventional method of pipe forming process be and the directly superimposed plastic film plate is configured to pipe Two edges, and transport it through welding section.Sweating heat is provided by circulating contact band of the energy source in overlapped surfaces Amount.The width of circulating contact band is 2mm to 40mm.Then pass through lap seams of the cooling zone by tube body by applying heat and pressure Weld together.
Laminated tube according to the present invention is formed by multi-layered board, which includes outer polyolefin layer, barrier layer, cohesion The main body of olefin layer, and the outlet positioned at main body one end.For the relationship between thickness, preferably the blocking thickness of tube body Degree is such as 7 microns to 30 microns, and the overall thickness of layered product is about 170 microns to 450 microns.All layers of plate are all firm Admittedly be adhering to each other.
The pipe seam generated in these laminated films is formed by method of superposition.In overlapping region, layered product side Inner membrance and the outer print film on another layered product side seal.Outer membrane and inner membrane material are made of the plastics of same type, otherwise it Latasuture cannot be formed.
Outer print film can be single-layer or multi-layer film, such as co-extruded films, laminated film etc., and can be printed on surface/ External or inside.Surface printing is carried out by conventional printing, such as flexographic printing, hectographic printing, silk-screen printing and embossing, and Inside printing is the intaglio printing on polyester film or polyethylene film.Polyolefin can be used for manufacturing outer membrane.
Barrier layer being total to by aluminium foil, polyamide, polyester, ionomer resin, polyvinyl product, ethylene and vinyl alcohol Polymers, metallised polyolefins, metallized polyester or cyclic olefine copolymer are made.
Inner membrance can be single-layer or multi-layer film, such as co-extruded films, laminated film etc..Polyolefin can be used for preparing inner membrance.This Afterwards, before pipe forming process, the multilayer film or plate that are subjected to outwardly and inwardly printing by painting protection.Gloss or matte varnish can As the paint in the present invention.
In order to realize latasuture desirable appearance and highly dense sealing strength, preferably edge is cut and is welded at a certain angle, It positions with inclining towards each other simultaneously.Preferably, layered product side is relative to the plane of layered product with 30 ° to 90 °, preferably 45 ° to 60 ° Angle chamfers and welds (Fig. 1).This overlapping welding also has the advantages that without additional plastic film strips cost.
For pipe forming process, usually using lamination tube producer by supplying heat and then cooling seam under stress Region forms lap seams.Another possibility is welded by ultrasonic wave, laser or heat and adhesive bonding method.Use tool There is radio frequency (RF) radiation source of independent inside and outside heater.Two radio-frequency generators allow for energy to be applied independently To the inside and outside of pipe.It is as shown in Figure 2 a using the gained seam of unimproved attachment.Since RF Sealing Method is to use In the most preferred method of longitudinal sealing pipe, therefore the improved machine part at heating and cooled region is for pipe of the invention It is invisible the result is that essential at the latasuture of body.The contact surface of circulating contact band at first and second heat energies is answered Long narrow degree 10mm is changed into from conventional length 15mm to 20mm.Increase subsequent cooling at cooling zone in addition, applying to weld Region obtains smooth surface.The pressure applied in traditional pipe formation machine remains unchanged.The fuzzy gap of seam region reduces, with It causes more visible.
Fig. 2 b shows the schematic diagram of the cross section at overlapping latasuture according to the present invention.Occur single line in top view, The surface of showed smooth.Latasuture surface does not have blocked up thickness, while keeping the aesthetics of outer surface and can bear breakage.
Fig. 3 shows the overlapping latasuture of the laminated tube of the scalpriform notch with various angles.As best shown in figures 3 a and 3b, exist Several a possibility that causing defect at the latasuture of laminated tube.One example is misalignment in cutting process.In cutting process not The reason of uniform cutting angle or stubbed blade are also these defects.Fig. 3 c is the photograph of laminated tube according to the present invention Piece, the laminated tube produce under 45 ° of scalpriform notch, and the length of contact surface is 10mm, and increases the cooling of cooled region. The gap not obscured at jointing line, and pipe has passed through the burst tearing test carried out at 2.0 bars 30 seconds.
Fig. 4 shows the latasuture of laminated tube according to the present invention, with different latasuture gaps.Within the long production time It is difficult to control the zero clearance of latasuture.This is because printing ink forms the heating source of device close to pipe.It needs carefully to monitor tubular The pipe of uniform quality is generated at the validity of device.
Fig. 5 and Fig. 6 shows the photo obtained from microscope, display: (A) sightless longitudinal weight according to the present invention Folded latasuture, is formed, institute and the imbricate of a line of laminate to be welded to the other edge of opposite side of laminate Stating laminate includes outer plastic layer, barrier layer and inner plastic layer identical with outer plastic layer material type, wherein laminated tube it is interior There is protuberance in overlapping region on surface, and do not have the protuberance in the overlapping region on the outer surface of laminated tube, so that pipe It is smooth as pipe is extruding pipe that the printed matter of surrounding looks as seamless and pipe surface；And by itself and following progress Compare: the overlapping latasuture of (B) existing pipe, the pipe all have protuberance and small outer gap in the inner surface and the outer surface, and (C) is existing There is the latasuture of pipe, the pipe all has protuberance and small outer gap, and the latasuture of (D) existing pipe in the inner surface and the outer surface, The pipe all has protuberance and small outer gap in the inner surface and the outer surface, this affects the beauty of printed matter.
